Cefepime, a potent cephalosporin belonging to the beta-lactam class of antibiotics, addresses a spectrum of bacterial infections caused by gram-negative and gram-positive organisms. Cefepime's efficacy is validated by FDA approval for conditions including pneumonia, complicated and uncomplicated urinary tract infections, skin and soft tissue infections, complicated intra-abdominal infections (in conjunction with metronidazole), and as an empiric treatment for neutropenic fever. The mechanism of action inherent to cefepime aligns with other beta-lactam antibiotics, disrupting bacterial cell wall synthesis. By covalently binding to key enzymes engaged in the final step of transpeptidation during peptidoglycan wall synthesis, cefepime induces structural defects in the cell wall, culminating in autolysis and the subsequent demise of the infectious organism. This module meticulously elucidates the indications, contraindications, adverse effects, dosing parameters, and monitoring considerations associated with cefepime. This educational resource empowers clinicians to leverage cefepime effectively in managing bacterial infections among hospitalized patients. Objectives: Identify the indications for cefepime therapy based on bacterial infection type, susceptibility patterns, and antibiogram data. Screen patients for risk factors such as age, renal impairment, and previous adverse reactions to cefepime to determine appropriateness for therapy. Apply pharmacokinetic and pharmacodynamic principles to optimize cefepime dosing and ensure therapeutic drug concentrations. Implement care with other healthcare professionals to ensure appropriate monitoring, management, and follow-up of patients receiving cefepime. Access free multiple choice questions on this topic.

In the event of a suspected overdose, the clinician should discontinue the drug or adjust the dose. Determining if the symptoms result from an actual cefepime overdose or preexisting comorbidities may be difficult. If suspicion is high or symptoms do not subside after dose adjusting or discontinuing, blood and cerebral spinal fluid levels should be obtained to evaluate if the toxicity stems from elevated cefepime levels. Cefepime-induced neurotoxicity (CIN) can lead to generalized periodic discharges and a triphasic wave pattern on EEG. Dialysis may be necessary in severe cases.[20]

Cefepime is a common antibiotic prescribed in the hospital setting. This drug is often prescribed empirically to septic patients before a pathogen is known, as it covers a broad spectrum of gram-positive and gram-negative bacteria. Therefore, all interprofessional healthcare team members must monitor each patient for immediate hypersensitivity reactions after initial administration. Clinicians need to bear in mind that the drug's pharmacokinetics can undergo alteration in patients with sepsis or renal dysfunction or in older patients, leading to undesired peaks and troughs and potentially severe adverse effects. If a patient exhibits a change in mental status or develops neurological signs such as seizure activity, cefepime should be discontinued, or dose adjustment may be required. These changes are more likely to occur in patients with sepsis or renal dysfunction and older adults. However, cefepime can be overlooked as a possible source as it is a common medication that is usually well tolerated; therefore, nursing is crucial to successful therapy with cefepime, as they administer the drug and are on the front lines and can report these issues to the ordering clinicians so appropriate action can be taken if necessary. Consultation with a neurologist may be required for cefepime-induced neurotoxicity. The clinician will decide to treat the patient with cefepime, but a consult with a pharmacist, particularly one with board certification in infectious disease, might be in order. Pharmacists can review the antibiogram and verify the dosing and duration. Nurses can counsel the patient on taking the medication, answer questions, monitor the patient and therapeutic effectiveness, and report any concerns to the prescriber. Cefepime therapy requires the collaborative effort of an interprofessional healthcare team, including clinicians, pharmacists, and infectious disease specialists, all working together and communicating across interprofessional lines to achieve optimal patient outcomes.
